Question

7. From a point on the ground, the angles of elevation of the bottom and the top of a transmission
tower fixed at the top of a 20 m high building are 45° and 60 respectively. Find the height of tower​

Answer 1

Answer:

Height = 14.64 m

Step-by-step explanation:

Let height of the tower be x m.

tan 45 = 20 / distance of point

1 = 20 / distance of point

Distance of point = 20m

tan 60 = (20 + x) / 20

$\sqrt{3}$ = (20 + x) / 20

20$\sqrt{3}$ = 20 + x

x = 20$\sqrt{3}$ - 20

x = 20($\sqrt{3}$ - 1)

x = 20(0.732)

x = 14.64 m
